5 Claims.

This invention relates to loom temple rolls, and more particularly toimproved roll structures having novel gripping surfaces for engaging theselvage edges of the cloth to move the same outwardly during the beatingup action of the lay.

One object of the invention is the provision of temple rolls havingfabric covered cloth engaging surfaces, which are provided with orcomprise spirally arranged raised portions forming ribs serving toengage and move the selvage edges of the cloth outwardly as the rollsare rotated by the forward movement of the cloth.

Another object of the invention is the provision in devices of thischaracter of a fabric covering for temple rolls formed from or havingincorporated therein a tractive or resilient material adapted to engageresiliently or grip the cloth as it presses into engagement therewithwithout forming roll marks in the selvage edges of the cloth.

A further object of the invention is the provision of devices of thischaracter formed with cores of substantially rigid material which areprovided with spirally ribbed surfaces having tubular fabric sectionssleeved thereon which form, with the ribbed surfaces of the core, faceprojecting spiral ribs for engaging the cloth.

Another object of the invention is the provision in devices of thischaracter of cloth engaging fabric surfaces which have been treated torender the fabric resistant to the action of acids, oils or alkalieswhich may be present in the fibres of the cloth being woven.

Other objects and advantages of the invention relate to various improveddetails of construction and novel arrangements of the parts as Will `bemore fully set forth in the detailed description to follow.

Referring to the drawing:

Fig. 1 is a top plan view of a portion of a loorrl temple, showing thesame in operative relation with cloth in the process of its formation ona loom, Fig. 2 is a side elevational view, partially in section, astaken along the line 2-2 of Fig. l, showing one operative position ofthe loom temple rolls in connection with a holder head of conventionaltype,

Fig. 3 is a side elevational view, partially in section, of one form ofroll structure embodying the invention,

Fig. 4 is a similar view of a somewhat modied form of roll structure,and,

Fig. 5 is a similar view of a further modified form of temple roll.

Heretofore, various forms and types of roll structures have beenprovided for use in loom temples toengage the selvage edges of the clothbeing woven for holding the edges outwardly and preventing abrasion ofor injury to the warp threads by the reed as the lay beam moves to beatup the threads. Devices of this character, as previously employed, rangefrom pin studded rolls to rolls having spirally ribbed toothed surfacesformed from a variety of materials. In the usevof rolls of the characterdescribed it is found that those having sharp cloth engaging faceportions tend to break `the threads and form holes in the selvage edgesof the cloth, while it is common for certain of such rolls to indent thecloth leavingmore or less permanent marks in the selvage edges, all ofwhich detracts from the .appearance and value of the cloth.

The present invention is adapted to overcome these defects'by providinga roll structure having a fabric cloth engaging outer surface which willnot injure or indent the formed cloth, even when using the finestthreads and forming the most fragile material. Y

In the form of the invention illustrated herein, l designates generallya loom temple, which may be secured to the breast beam of a loom in theusual or any suitable manner, and which comprises a head 2 having a podportion 3 and cap 4 for receiving loom temple rolls 5 which may berotatably supported by shafts 6 suitably mounted in the end walls of thepod 3 or cap 4 of the loom temple head. The cap 4 may be mounted foradjustment towards or from the pod 3 and secured in the desired adjustedrelation relative thereto by screws or bolts 1. As shown in Fig. 1 ofthe drawing, the cloth being formed is indicated by the'reference1character 8 and is engaged by the temple rolls slightly in advance ofthe fell 9.v

The temple roll 5 shown in Fig. 3 of the drawing comprises a core l0formed with a shaft receiving opening I l extending therethrough, whichkcore may be formed from wood or any other suitable natural or syntheticmaterial adapted for the purpose and may have a rigid or slightlyresilient outer surface as maybe found desirable lin practice. In theform of thel invention shown in Fig. 3 of the drawing, the core Hl isprovided with an enlarged rounded central portion I2, up-

on which` are formed one or more raised spiral `vmaterial is sleevedover the enlarged central portion l2 of the core and has ends Ilextending outwardly therefrom and adapted to be engaged and held bymetal caps I8 mounted on the reduced ends l1 of the core portion oftheroll.

The inner ends I9 of the metal caps I8 may bel spun down over theadjacent ends I1 of the fabric I 8 to hold the fabric cover firmly inposition upon the enlarged central portion l2 of the core. The oppositeend 20 of each cap I8 is inturned to fit over the free end of itsrreduced end portion i5, as shown at theright in'Fig.l3 of the drawing.The raised spiral rib or ribs i4 formed on the -central porti-on l2 ofthe core press the tubular fabric section I6 outwardly to V' form araised spiral rib or ribs 22 therein for engagement with the cloth toholdn the ycentral portion thereof taut as the rolls are frotated bysuitable lacquer or proofing ,materiaL such as Bakelite, to render thefabric impervious to the action of -a-cids or alkalis which maybepresent in the cloth being formed. I may also incorporate threads orstrands of tractive material,

such as rubber, asbestos, BunafS, Koroseal, or

Neoprene in the woven or braided tubular Vsections to give them addedtraction upon the cloth.

In the form of the inventionshown `in Fig'. 4 of the drawing, the roll24 comprses'a core" 25 having a shaft receiving opening 26 formedtherein and shaped to provide anenlarged central cylindrical portion 21and reduced ends 28'.v The enlarged central portion 21 may haveV acylindrical outer surface L29 to receive a tubularfabric section 3U,which may be woven, braided or Aotherwise formed, and which, as shown,has incorporated therein a spirally positioned cord or enlarged strand32 woven, braided or otherwise embodied within the tubular fabricsec-tion. Metal caps 33 lare fitted over the reduced ends 2B, and

tion 30 to hold the same firmly in position upon l the enlarged centralportion 21 of the core.'`

In the form of the invention shownV inl-Fig. 5 of the drawing, the roll35 has a core member 36 provided with a shaft receiving opening 31, :andis of a shape similar ,to that shown in Figfl of the drawing, having acentral enlarged cylindrical portion 38, having a cylindrical outer face39, and reduced end portions .40. In this form of the inventiona tubularfabric cover 42 may, as invthe preceding forms, be woven,A braided orotherwise formed, and is shown as provided with a plurality of slightlyraised thread portions 44 which are 'spaced from each other and sopositioned in the tubular fabric ast-to form together one or moresubstantially continuously extending, spirally arranged, raised, clothengaging areas in the tubular fabric which projectfoutwardly slightlybeyond the remaining surface of the tubular fabric to engage thevselvage edges of the cloth being formed and rmove lthe Same outwardly asthe rolls are rotated through'movement of the cloth. In this, as in theforms previously shown, metal caps 46 may be employed having ends forcedinto engagement with or spun over the free ends =41 of the tubularfabric cover 42 to hold the fabric -cover securely in position upon theenlarged central portion 38 of the core In each form of the invention,the tubular fabric cover may be made from any suitable or desired formof woven, braided or knitted fibrous material, vvsuch as, silk, rayon,cotton, ramie, or thelike, and may have incorporated therein filamentsor threads of rubber, asbestos, or other material adapted to exert atractive force on the surface of the cloth being formed. The tubularvfabric may be and is preferably treated, espe- Y cially when formedfrom a single fibrous material, such as cotton, wool, rayon or the like,by being partially or ywholly impregnated with a suitable lacquer, orthe like, such as Bakelite, to render the fibres more or less imperviousto the action of acids, oils or jalkalis, which may be present in thecloth being formed and in order to preserve the fabric material againstdistortion. Ineach case, the tubular fabric material may be firmlysecured to the enlarged central portion oi the core member by beingglued or otherwise secured thereto throughout all or a portion of itsextent so that'it will maintainv an even surface throughout, or it maybe secured thereto only at the outer ends, as by means'of thel metal endcaps.

In the forms shown in Figs. 4 and 5, the spirally positioned heavy cordor thread 29 and the enlarged or raised thread portions 44 may be formedfrom orv contain threads of rubber, Neoprene; Buna-S,l Korose'al,asbestos fibres or the like, or from anyother suitable form of' threador cord adapted to exert ahigh tractive eectV upon the cloth beingformed'.

In each form of the invention shown the rolls may be positioned in theholder to engage either the top or, bottom surface of the cloth beingformed,'or they may be arranged to engage opposite side faces of thecloth, as has been the practice heretofore with various forms of templerolls.

What I claim is: v A Y 1. A loom temple roll comprising AaYsubstantially cylindrical core member, and a tubular cover formed fromstrands cylindrically interlaced together throughout the longitudinaland circumferential extent of the tubular shape sleeved upon the coremember and having a raised spiral rib portion formed therein andprojecting outwardlyradially of the tubular cover beyond the remainingsurface portionsthereof when the tubular cover member is in positionupon said core member.
